actual vehicle behavior. If the two do not match, for example when
th e vehicle begins to skid, ESP brakes the appropriate wheel auto­
matical ly .
The vehicle is stabilized again by the forces acting on the wheel
during braking. With an oversteering vehicle (tendency for the rear
end to skid out of the curve), the brake application is mainly at the
front wheel on the outside of the curve, with an
understeering
vehicle (tendency to run wide in the curve) at the rear wheel on the
inside of the curve or additionally at the other wheels as needed.
This brake application is accompanied by noises.
ESP works in conjunction with ABS=>
page 192. If there is malfunc ­
tion in the ABS, ESP is also inoperative.
Activating
The ESP is automatica lly activated when the engine is started, and
it performs a self-test. As soon as the test is completed, the system
is in normal operating mode. With ASR deactivated, or with ESP/ASR
deactivated, pressing the button=>
page 188, fig. 158 returns the
system to normal operation.
Deactivating
ESP should normally be activated at all times because this ensures
optimum vehicle stability. Only in certain exceptional cases it does
make sense to deactivate Anti-Slip Regulation (ASR) or the Elec­
tronic Stability Program (ESP) by pressing the button =>
page 188,
fig. 158. Both deactivation stages can only be activated from normal
mode .
Deactivating ASR
Tap the switch. Deactivation is indicated by slow flashing of the ESP
lamp in the instrument cluster. In certain situations (e .g. driving
with snow chains, in deep snow or on loose ground, or when
rocking the car free), it may be necessary to deactivate ASR.
Deactivating ESP/ASR
Press the button for more than 3 seconds. Deactivation is indicated
by the ESP lamp in the ins trument cluster staying on permanently.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
This
deactivates the Electronic Stability Program (ESP) in addition to
ASR. No Elec tronic Stability System operation and no Anti -Slip
Regulation is available across the entire speed range; ASR and ESP
are activated only when the brakes are used for the duration of the
braking action and remain active until a stable vehicle condition has
been reached. There is no driving situation which requires ESP to be
deactivated, so this should only be done if the driver's skill and the
traffic situation permit.
& WARNING
• The limits of physics cannot be suspended by ESP. Even in vehi­
cles with ESP. you should always adapt your driving to road and
traffic conditions. This is particularly true on a slippery and wet
road . Do not be tempted by the increased safety provided to take
risks -danger of an accident!
• Please note that when ASR or ESP /ASR is deactivated , the drive
wheels can spin on icy and slippery roads and the vehicle can
break away -danger of skidding!
Electronic differential lock CED1
.)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The elect ronic differential lock (EDU helps the car to start moving,
accelerate and c limb a gradient on surfaces providing poor or
a lmost no grip. Without EDL, this would be difficult, if not impos ­
s ible.
How the system works
The EDL operates automatical ly. It monitors the rotationa l speed of
the drive wheels on an axle with the help of the ABS sensors
=>
page 192. If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground
on
one side),
the spinning wheel is braked, thereby transferring power

to the other drive wheel or wheels (all-whee l drivel. This is done up
to a speed of about 60 mph (100 km/h). Noises from the brake
system signal that wheel spin is being controlled.
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface
with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move. The wheel less able to transfer
power spins .
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily. The
vehicle remains operational and behaves in the same way as a
vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your
ability to control your car. -Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning. This is
indicated by the ABS warning light=>
page 16. •
Anti-Slip Regulat ion System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP) . When the vehicle starts up and acceler­
ates, the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface.
How the system works
ASR performs automatically, i.e. without the driver's intervention.
With the aid of the ABS sensors=>
page 192, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque is reduced automatically until the tires find enough grip to
lock onto the road surface. The system is active across the entire
speed range.
Th e ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
Activating
The ESP is automatically activated when the engine is started and it
performs a self -test. You can activate a deactivated ASR if required
by pressing the=>
page 188, fig. 158 button. When it is activated,
the message
ESP/ASR on appears briefly in the display.
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=>
page 188, fig . 158. With the ASR deactivated,
the ESP check light comes on, see=>
page 13. The message ASR off
appears in the display as well.
The ASR should normally be activated all the time . Only in certain
exceptional situations when some slip is desirable does it make
sense to deactivate the ASR. Examples:
• when driving with tire chains

• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck.
When the abnormal situation is over, you should activate the ASR again.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i J Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when this is not desired.

Braking
Generat information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending largely on operating conditions and driving habits~& .
On vehicles that are either driven mostly in stop-and-go city traffic
or are driven hard, the brake pads should be checked by your autho­
rized Audi dealer more often than specified in the
Warranty & Main­
tenance booklet.
Failure to have your brake pads inspected can
result in reduced brake performance.
On steep slopes, you should use the braking effect of the engine.
This way, you prevent unnecessary wear on the brake system. If you
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
must use your brakes, do not hold the brakes down continuously.
Pump the
brakes at intervals.
Moisture or road salt
If you are driving faster than 50 mph (80 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regular intervals so as to improve reaction time when braking on
wet surfaces. You, the driver, will not notice anything .
Under certain conditions, for example, when driving through water
or very heavy rain, or even after washing your vehicle, the braking
effect can be reduced due to moisture (or in freezing conditions ice)
on the brake pads. A few cautious brake applications should dry off
the brake pads or remove any ice coatings .
The effectiveness of the brakes can be reduced when the vehicle is
driven on a salt-covered road and the brakes are not used . Likewise,
you clean off accumulated salt coating from brake discs and pads
with a few cautious applications of the brake~&.
Corrosion
There may be a tendency for dirt to build up on the brake pads and
corrosion to form on the discs if the car is not driven regularly or
only for short trips with little use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
firmly a few times from a moderately high speed~& .
Faults in the brake system
If you should notice a sudden increase in brake pedal travel, then
one of the two brake circuits may have failed~ &.
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is
too low. The brake fluid level is monitored electronically.

Brake lining wear status
Brake lining wear may be checked by visual inspection of the condi­
tion of the brake pads through the openings in the wheel. If neces­ sary, the wheel may be removed for this inspection=> page
270,
"Wheel change" .
L1}. WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road conditions permit. Other
road users must not be put at risk -you may cause an accident!
• Before descending a steep grade, reduce speed and shift trans­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often. This could
cause the brakes to get hot and diminish braking efficiency.
• Do not "ride the brakes" by resting your foot on the pedal when
you do not intend to brake. This may cause the brakes to overheat,
premature wear and increased stopping distance.
• Under certain climatic and operating conditions such as
passing through water, driving in heavy rain or after washing the
vehicle, the effectiveness of the brakes can be reduced. In winter,
ice can accumulate on the brake pads, linings, discs and drums.
Carefully apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt-covered roads
without using your brakes can also affect braking efficiency. Clean
off accumulated salt coating from brake discs and pads with a few
careful brake applications.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes is not obstructed.
Otherwise the brake system could overheat reducing the effective ­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping distance. Avoid driving the
& WARNING (continued)
vehicle and have it towed to the nearest authorized Audi dealer or
qualified workshop. •
Brake booster
The brake booster adds extra braking power.
The brake booster works with vacuum pressure which is created
only when the engine is running=>& .
L1}. WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake booster is not working, for example when towing
your vehicle, or because the brake booster has somehow been
damaged, the brake pedal must be pressed considerably harder to
make up for the lack of booster assistance. •
Func ... ion=ng of Anti-Lock Brake System (ABS)
ABS prevents the wheels from locking up under braking.
The ABS contributes effectively to vehicle control since it prevents
the wheels from locking when the brakes are applied. This means
that the vehicle remains steerable and is less likely to skid.
With ABS you do not need to pump the brake. Just hold the brake
pedal down.
However, do not expect that the ABS shortens braking distance
under
all circumstances . When driving on gravel or on newly fallen
snow on top of icy surfaces, braking distance may be even longer,
therefore, under these circumstances, it is especially important that
you drive slowly and with great care. .,_

How the ABS system works
An aut omatic check is made whe n a speed of ab out 4 mph (6 km/h)
is reached. When this happens, a pumping noise can be heard.
I f an individua l wheel begins to rotate too slowly in relation to
ve hicle speed and ten ds to lock, the A BS automatical ly reduces
brake pressure to prevent that wheel from locking.
T his auto matic adjust ment p rocess wil l cause a
slight vibration o f
the brake peda l and some noises to alert you that veh ic le speed
must be ada pted to e xisting roa d and traff ic c onditions.
& WARNING
Although the ABS is very effective , always remember that braking
c apability is limited by tire tra ction . Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking e xtra risks .
The ABS cannot overcome the laws of physics.
[ i ) Tips
• I f ABS is not functioning properly, a warning light wil l come on.
See
=> page 16.
• I f a fau lt occurs in the ABS, the E DL is als o not fu ncti onin g. This

Brake assistant
The brake a ssi st ant is de sig ned to a chieve th e opti mum
b ra kin g eff ec t.
The brake assistant helps to increase the effective braking power
and thus to ac hieve a s horte r stop ping dis tance. If the drive r
presses the brake pedal very quick ly, the brake assistant automati ­
ca lly b oosts the braki ng force to the maximu m level, up to th e point
where the anti -loc k brake function (A BS) intervenes to stop the
whee ls from loc king. You should then keep the brake pedal pressed

& WARNING
Please remember that the accident risk always increases if you
drive too fast , espe cially in corners or on a slippery road , or if you
follow the vehicle ahead of you too closely . An increased accident
risk cannot be compensated even by the brake assistant , so
always maintain a safe speed. •

New brake pa_ds
Remember that new brake pads do not have a full braking
effect during the first 250 miles (400 kilometers) after they
are installed.
New brake pads have to be "burnished in" before they have optimal
grab =>& .
During the break -in period, you should avoid putting severe loads
on the brakes . Severe loads include, for example, sudden hard
braking, in particular at very high speeds or, for example, on moun ­
tain passes .
& WARNING
Until they develop the maximum "bite" for best stopping power,
the surfaces on new brake pads require some "breaking-in" during
the initial 100 to 150 miles (150 to 200 kilometers) of normal city
driving. You can compensate for this by pressing the brake pedal
more firmly. This applies whenever new pads are installed. •
Driving through water on roads
Note the following to avoid vehicle damage when driving through
water, for example on flooded roads:
• The water must not be any higher than the bottom of the vehicle
body .
• Do not drive faster than walking speed .
& WARNING
After driving through water, mud, slush, etc., the brakes may be
slow to take effect because of wet brake rotors and pads. Dry the
brakes first by braking carefully to restore the full braking effect .
0 Note
Vehicle components such as the engine, transmission , suspension
or electrical system can be severely damaged by driving through
water .
[ i] Tips
• Check the depth of the water before driving through it .
• Do not stop th e vehicle, drive in reverse or switch the engine off
when driving through water.
• Keep in mind that oncoming vehicles may create waves that
raise the water level and make it too deep for your vehicle to drive
through safely.
• Avoid driving through salt water because it can cause
corrosion. •
Catalytic converter
It is very important that your emission control system
(catalytic converter) is functioning properly to ensure that
your vehicle is running in an environmentally sound
manner .
- Always use lead-free gasoline~ page 217, "Fuel supply".
- Never run the tank down all the way to empty.
- Never put too much motor oil in your engine ~ page
230,
"Adding engine oil 'l:::r.".
- Never try to push -or tow -start your vehicle.
Th e ca taly tic conv ert er is an ef ficient "clean-up " device built into the
exhaust system of the vehicle . The catalytic converter burns many
of the pollutants in the exhaust gas before they are released into the
atmosphere. •

Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
etc., make certain that low -lying parts such as spoilers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low -slung chassis (sports
chassis) and fu lly loaded vehicles.
Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
o f your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and tires largely depend on three factors:
• your personal driving style
• operating conditions
• technical limitat ions
If you anticipate what you need to do next and drive economically,
you can easily cu t your fue l consumption by 10 -15 percent . This
section will give you some tips on how you can help the environ­
ment and your pocketbook .
[ i ) Tips
The consumption estimates as published by ENVIRONMENTAL
PROTECT ION AGENCY (EPA) and Transport Canada may not corre­
spond to your actua l consumption on the road, which wi ll vary
depending upon vehic le load and speed, road and weather condi ­
tions, trip length, etc.
Drive smo~thly and keep a lookout ahead
Vehicles use the m ost fuel when they are accelerating.
Avoid unnecessary accelerating and braking.
Vehicles use the most fue l when they are accelerating . If you antici­
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible -for
example when you see that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
-Try and keep we ll below your car's maximum speed.
Acce lerating gently reduces fuel consumption, engine wear, and
does not disturb the environment .
Fuel consumption, exhaust em issions and engine noise increase
disproportionately at high speeds. If you drive at approximately
three quarters of top speed, fuel consumption wil l be reduced by
one half. Never drive faster than the posted speed limit and weather
conditions permit .•
Reducing unnecessary idling
E ven when your car is just idling i t burns up fuel.
- Sh ut the eng ine off when you are not driving the vehicle.
- Do not warm up th e vehicle by letting the eng ine r un at
idle.

Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor­
tation.
If you plan to tow a trailer, please remember that the additional load
wi ll affect durability, economy and performance.
Trai ler towing not on ly p laces more stress on the vehicle, it a lso ca lls
for more concentration from the driver.
For this reasons, always fo llow the operating and driving instruc ­
tions provided and use common sense. •
Technical requirements
Traile r hit ch
Use a weight -carrying hitch conforming to the gross trailer weight.
The hitch must be suitab le for your vehicle and tra iler and must be
mounted secure ly on the vehicle's chassis at a
technically sound
location . Use only a trailer hitch w ith removable ball mount. A lways
check with the trai ler hitch manufacturer to make sure that you are
using the correct hitch .
Do not use a bumper hit ch .
The hitch must be installed in such a way that it does not interfere
w ith the impact-absorbing bumper system . No modifications
should be made to the vehicle exhaust and brake systems. From
time to time, check that all hitch mount ing bolts remain securely
fastened.
When you are not towing a trailer, remove the trailer hitch ball
mount. This prevents the hitch from causing damage should your
vehic le be struck from behind
=:> & .
Tire pre ssure
When towing a trailer, inflate the tires of your vehic le to the cold tire
pressure listed under "Full load"on the sticker on the right door­
jamb. Inflate trai ler tires to trai ler and tire manufacturers' specifica ­
tions.
Lights
The head ligh t settings should be checked wit h the trai ler attached
before driving off. Have the head lights adjusted as necessary so
t hat you can see the road ahead but not blind oncoming traffic.
Check to make sure both vehicle and trailer lights are working prop ­
erly.
Engin e cool ing sy stem
Towing a t rai ler makes the engine wo rk ha rder . It is important that
the cooling system's performance stands up to the additiona l
strain. Make sure that the coo ling syste m has enoug h fluid.
Traile r br akes
If your traile r is equipped wi th a braking system, check to be sure
that it conforms to al l regu lations.
T he trailer hydraulic brake system must not be directly connected to
the vehic le's hydrau lic brake sys tem.
Safety chai ns
Be sure trailer safety chains are properly connected from the trailer
to the h itch on the vehicle. Leave enough slack in the chains to
permit turning corners. When you install safety chains, make sure
they will not drag on the road when you are driving.
The chains should cross under the trailer tongue to prevent it from
dropping in case of separation from the hitch. _.

Trailer lights
Trailer lights must meet all regulations. Be sure to check with your
authorized Audi dealer for correct wiring, switches and relays.
Mirrors
If you are unable to see the traffic behind you using the regular
outside mirrors, then you
must install extended mirrors. It is impor­
tant that you
always have clear vision to the rear .
& WARNING
After removing the trailer hitch, do not store it in your vehicle. In
case of sudden braking, the hitch could fly forward and injure you
or your passengers .

Weig ht dis tributi on
Towing a loaded trailer with an empty car resu lts in a high ly
unstable distribution of weight . If this cannot be avoided drive at
very low speeds on ly to avoid the risk of losing steering control.
A "ba lanced" rig is easier to operate and control. This means that
the tow vehicle should be loaded to the extent possible and permis ­
sib le while keeping the trai ler as light as possib le under the circum ­
stances. Whenever possible, transfer some cargo to the luggage
compartment of the tow vehicle while observing tongue load requirements and vehicle loading considerations .
Speed
The higher the speed, the more difficult it becomes for the driver to
control the rig . Do not drive at the maximum permissible speed.
Reduce your speed even more under unfavorable load, weather or
wind conditions -particularly when going downhill.
Reduce vehicle speed
imm ed ia tely if the trailer shows the sl ightest
sign of swaying. Do not try to s top the s wayi ng by a ccelerating .
Observe speed limits . In some areas speeds for vehicles towing
trai lers are lower than for regular vehicles.
Always app ly brakes early. When driving downhill, shift into lower
gear to use the engine braking effect to slow down the vehicle. Use
of the brakes alone can cause them to overheat and fail.
C oo la nt tempe ra tu re
The coolant temperature gauge ~ page 9 must be observed care ­
ful ly. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or switch off the air condit ioner.
If the coolant temperature warning light in the instrument cluster
starts flashing -~-, pull off the road, stop and let the engine
idle for
about two minutes to prevent heat build -up .

Trailer towing tips
Important to know
Your vehicle handles different ly when towing a trailer because of
the additional weight and weight distribution . Safety, performance
and economy w ill great ly depend on how carefu lly you load your
trailer and operate your rig.
Before you actually tow you r trailer, practice turn ing, stopping and
backing up in an area away from traffic. Keep practicing unti l you
have complete ly become familiar with the way your vehicle -trailer
combination behaves and responds .
Backing up is difficult and requires practice. Backing up with a
trailer genera lly requires steering ac tion opposite of that when
backing up your vehicle without a trailer .
Maintain a greater distance between your vehicle and the one in
front of you. You will need more room to stop.
T o compensate for the trailer, you wi ll need a larger than normal
turning radius .
When passing, remember that you cannot accelerate as fast as you n ormal ly wou ld because of the added load . Make su re you have
enough room to pass. After passing, al low plenty of room for your
trailer before changing lanes again .
Avoid jerky starts, sharp turns o r rapid lane changes.
